The GRACO 15W661 is a manifold block designed to accommodate either a GL-32 grease injector or a GL-43 oil injector, constructed from carbon steel. It is intended for use in centralized lubrication systems for on-road vehicles and off-road equipment, facilitating precise delivery of lubricants to critical points.

Key Features:

• Injector Manifold Block
• GL-32 (Grease) / GL-43 (Oil), 1 Injector, 1/4 in. NPT
• Carbon Steel
• GL-32: 5.3–24.1 MPa (750–3500 psi); GL-43: 5.3–6.9 MPa (750–1000 psi)
• Compatible with GRACO GL-32 grease injectors and GL-43 oil injectors; for use with grease (GL-32) or oil (GL-43)
• Single injector configuration for targeted lubrication
• Robust carbon steel construction for durability
• Visual cycle indicator for easy monitoring
• Adjustable for precise lubrication control
• Designed for reliable operation in demanding environments

Applications:
Centralized lubrication systems for on-road vehicles and off-road equipment, including mining, agriculture, and industrial machinery.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper thread engagement for the 1/4 in. NPT inlet
• Verify compatibility with the intended injector (GL-32 for grease, GL-43 for oil)
• Follow manufacturer torque specifications for secure installation
• Regularly inspect for leaks and proper injector function
• Consult the manual for specific installation and maintenance procedures
